Working inside the node with the power on
When you are servicing the SAN Volume Controller node, you might need to turn on the node while the cover is off.
Before you begin
Attention: Static
electricity that is released
to internal components when the node is turned on might cause the
node to halt, which might result in the loss of data. To avoid this
potential problem, always use an electrostatic-discharge wrist strap
or other grounding system when you work inside the node with the power
on.

You might be instructed
to turn on
the node and look at system-board LEDs while the cover is off. Follow
these guidelines when you work inside a node that is turned on:
- Avoid wearing loose-fitting clothing on your forearms. Button long-sleeved shirts before working inside the server; do not wear cuff links while you are working inside the node.
- Do not allow your necktie or scarf to hang inside the node.
- Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist watches.
- Remove items from your shirt pocket, such as pens and pencils, that could fall into the node as you lean over it.
- Avoid dropping any metallic objects, such as paper clips, hairpins, and screws, into the node.
